    Hi folks,

    Ubuntu-6.06.1_LAMP-server-amd64

    Connection:
    Server --> Router --> Modem --> ISP

    The connection to Internet is running fixed/static IP. I have domain registered. I suspect the router which was supplied and presetup by ISP on loan, has been locked by ISP. The internel IP of the server is 192.168.0.10. IP address 192.168.0.1, LAN, on the router is locked by ISP. Typing 192.168.0.1 on browser requested login and password. Typing admin login and password did not work.

    Now I'm prepared to build my own gateway including firewall on an old PII box. The new connection will be;
    Server --> Gateway --> Modem --> ISP

    The router will be removed for other use, not necessary going through 2 gateway.

    Please advise what information are needed from ISP to setup my own gateway. What is the reason for ISP to lock IP address 192.168.0.1 on the router which is on my LAN.

    TIA

    There are three IP ranges which are strictly for internal usage and which should never be exposed to the internet. The ranges are
    Code:
    10.0.0.0 - 10.255.255.255
    172.16.0.0 - 172.31.255.255
    192.168.0.0 - 192.168.255.255
    As you can see your IP address is in this range. It's private space and is used behind a router. The router uses the NAT protocol to translate multiple internal IP addresses to the external address, and directs returning packets back to the originator. Maybe this will give you a start with how and why.
